Article describe the preparation of cells for correlative electron microscopy after live light microscopic observation of fluorescently labeled cytoskeletal proteins microinjected into the same cells. Since identification of cytoskeletal elements in electron microscopic preparations is an essential part of any correlative study, procedures for immunogold labeling of cytoskeletal components and for myosin S1 decoration of actin filaments are also described. - [Read Electron Microscopy of the Cytoskeleton of Cultured Cells]
In brief, the reaction mixture, is prepared in exactly the same way as if the sample is to be stained or shadowed for electron microscopy, but once the...

Caenorhabditis elegans, a small (adults are ~1 mm long), free-living soil nematode that feeds on bacteria, is an ideal organism for applying various live microscopy techniques. This protocol describes useful techniques for preparing C. elegans for live microscopic analysis. Details of sample preparation depend on the developmental stage of the worm to be studied. - [Read Live Imaging of Caenorhabditis elegans: Preparation of Samples]
Protocol describes a method for the evaluation of mitochondrial function using the fluorochrome CMXRos. CMXRos is sequestered by actively respiring mitochondria, but washed out when the mitochondrial membrane potential is lost. This analysis can be combined with the TUNEL technique or immunocytochemistry. - [Read Microscopic Analysis of Mitochondrial Transmembrane Potential Protocol]
